Problems solved by technology

At present, there are some researches on voriconazole freeze-dried powder injection. Among them, some studies have found that adding preservatives commonly used in ophthalmology (benzalkonium chloride, benzalkonium bromide, cetrimonium bromide, phenoxy After the preparation of ethanol, p-hydroxybenzoic acid lipids, chlorobutanol), there is almost no inhibitory effect on bacteria, which does not meet the bacteriostatic requirements of ophthalmic preparations. times), also can not improve the b

Abstract

The invention belongs to the field of pharmaceutical preparations, and particularly relates to an ophthalmic composition. The composition comprises the following components in parts by weight: 0.5-5 parts of voriconazole and/or medicinal salt thereof, 8-35 parts of a solubilizer and 0.1-4 parts of polyvinyl alcohol. The invention also relates to a method for preparing the ophthalmic composition and application of the ophthalmic composition. The ophthalmic composition is high in stability and low in eye irritation, does not contain preservatives, and has a good prevention or treatment effect onfungal infectious diseases of eyes.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, specifically relates to an ophthalmic composition, and also relates to a preparation method and application of the ophthalmic composition. Background technique [0002] Ocular fungal infectious diseases include fungal keratitis, fungal conjunctivitis, fungal blepharitis, etc. Among them, fungal keratitis has a high incidence and blinding rate, and has become a common blinding eye disease in my country. The main pathogens are Fusarium and Aspergillus. Due to the long treatment cycle and easy recurrence after ocular fungal infection, there is an increasing demand for therapeutic drugs with good clinical efficacy and broad antibacterial spectrum. Currently, the commonly used topical antifungal drugs in ophthalmology include polyene antifungal drugs and triazole antifungal drugs. Among them, the product representative of polyene antifungal drugs is natamycin eye drops, which is the only a...
